Alabama’s Republican run-off for U.S. Senate brought a second visit from the White House in less than a week.

Vice President Mike Pence spoke to a crowd in Birmingham for about twenty minutes Monday night, rallying in support of Luther Strange. His speech began less than twelve hours before polls open across Alabama.

Pence focused on his agenda with President Donald Trump, specifically repealing and replacing Obamacare. Pence said he believes Strange can help accomplish that agenda, if elected to the U.S. Senate.

The vice president's trip comes just days after President Trump made a trip to Alabama to campaign for Strange in Huntsville.

Pence said he wanted to be clear. He and the president are not campaigning against anyone. They just want to support Strange.

Former Governor Robert Bentley appointed Strange to the seat vacated by Jeff Sessions earlier this year. The White House wants to keep him in Washington.

Strange’s campaign is hoping their support can help at the polls tomorrow.

“I’m here today because I know Senator Luther Strange will be there for the President,” said Pence. “Because he's already been there. As you heard the President say Friday night, he stood with us every step of the way. So on President Trump's behalf, I’m here to ask Alabama to do everything you can to send Luther Strange back to Washington, DC.”

A representative from Strange’s campaign told ABC 33/40 he was not worried about two new polls that have Moore ahead. He said the campaign is feeling optimistic going into Election Day.

One key part of this race will be voter turnout. Secretary of State John Merrill is expecting just 12-15 percent turnout.
